SHOE-FINISHING- APPARATUS.

1,011,904, Specification of Letters Patent.

Patented Dec. 19, 1911. Application filed April 1, 1911. Serial No. 618,835.

To all whom it may concern 13 whose ends pass through holes in the lugs 15 and enter sockets 17 formed in the abut- Be it known that I, ARTHUR BATES, a subject of the King of Great Britain, residing at Leicester, Leicestershire, England, have invented certain Improvements in ShoeFinishing pparatus, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to apparatus for use in finishing boots and shoes and in particular to certain improvements in the con struction of finishing rolls which adapt them to perform more efliciently than heretofore operations in the process of reforming the soles and uppers of turn shoes.

An important feature of the invention consists in the combination with a finishing roll or other tool of novel means for heating the same by friction. "As embodied the tool is an ironing roll which is driven and is formed with a concentric aperture opening outwardly from one end. Within this aperture are wedge members which are formed with oppositely inclined inter-engaging faces and a spring is arranged to exert a continual pressure tending to slide the wedge members in the direction to expand them against the walls of the aperture. Either the roll or the friction wedge members may be rotated to produce the necessary relative movement and means is provided to regu-' late adjustably the tension of the spring.

Figure 1 is a side elevation; Fig. 2 is a bottom plan view.

A suitable support or pedestal 1, sustains a yoke 4, which is provided with trunnions 8 to pivotally support a sleeve 3, constituting a bearing for the driving shaft 2. The shaft 2 is shown as having on one side of the sleeve a fast pulley 10 to receive power through a belt from any suitable source. 011 the other side of the bearing 3 a second sleeve 5 surrounds the shaft and is secured thereto by pins 6, or any other suitable means, said sleeve having at its ends, the flanges 7, which constitute abutments for the work engaging members 9 of the beater roll. The work engaging members are shown as being in the form of bars having inwardly extending lugs 15 which fit against the inner opposed surfaces of the abutments 7, to which they are pivotally connected by pins ments 7.

The heated smoothing or ironing tool 20 is shown as located at the right hand end of the shaft 2, this tool being int-ended to be employed for ironing and smoothing out the upper of a shoe, to remove the wrinkles and to impart a finish to certain portions of the shoe, as for instance, along the shank and in the crease formed between the upper and sole, where, by reason of its shape, the beating tool is not adapted for operation. The tool 20 is shown as beingcurved appropriately for fitting the convex portions of the upper, and terminates at the rear in a relatively thin edge 200 which is shaped to enter the rand crease, or the crease formed between the upper and sole at the shank. The inner end of the ironing tool is supported from the flange 7 of the beater-roll nearest the right hand end of the shaft 2, as seen in Fig. A collar 22, secured to the shaft bearing 3, supports through a pivot 23 one end of a bent rod 24, and the opposite end of this red is attached to a bracket 26 by a screw 27. The outer end portion of the bracket 26 is arranged to fit against the outer end of the tool 20, and is perforated to receive a rod 28. The tool 20 is provided with a cavity to receive two friction members 30 which are formed with wedge-shaped engaging faces 31. A coil spring 33'is located in a recess between the friction members 30, and has its inner end attached to one of said members and its outer end attached to the inner extremity of the pin 28, as shown by dotted lines in Fig. 1. The outer end portion of the pin 28 is provided with a r screw thread to which is applied an adjusting nut 32, which bears against the bracket 26 and acts to control the tension of the spring 33. By turning the nut more or less, the friction members are caused to expand and grip the inner surface of the tool 20 to the extent desired. The devices just described serve to support the outer end of the ironing tool and particularly the friction heating devices 30 which are restrained from rotation with the ironing tool 20 by the pins 35 which extend from the bracket 26 into the thick outer end of the lower mem ber 30.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. A device of the class described having, in combination, a driving shaft, a finishing roll having one end supported from said. shaft, wedge-shaped engaging members arranged in said roll, a bracket having bearing against the other end of said roll, a support for said bracket, a rod extending through said bracket, a yielding device connecting the inner end of said rod with one of said members and acting to effect frictional engagement between said members and the roll, and an adjusting nut on the outer end of said rod.

2. A machine of the class described having, in combination, a frame, a shaft journaled in the frame, an ironing roll mounted on a freely projecting end of the shaft, a bracket extending from the frame around the roll to its free end, and friction heating means supported by said. bracket and arranged within the roll.

3. A machine of the class described having, in combination, a frame, a shaft journaled in the frame, an ironing roll mounted on a freely projecting end of the shaft and having a chamber concentric with the axis of the roll, wedge blocks forming together substantially a cylinder and having adjacent oblique faces arranged within the roll, and means acting longitudinally of the axis of the roll to expand the wedge blocks and hold them in friction heating engagement with the roll.

4-. A machine of the class described having, in combination, roll driving means and a shoe finishing roll having an outer face shaped to adapt it for operation on different portions of a shoe and a chamber extending substantially the length of said face, friction heating means within said chamber and having engagement with the roll in opposed radial directions and throughout substantially the length of the working surface of the roll, and a support to hold the friction means against rotation with the roll.

5. A machine of the class described having, in combination, a shoe finishing roll having an outer face shaped to adapt it for operation on different portions of a shoe and a concentric chamber extending substantially the length of the roll, wedge members forming an obliquely split cylinder located within said chamber, means for supporting said wedge members and holding them against rotation with the roll, and means tending yieldingly to move said members relatively in the direction to expand them for producing friction heating engagement with the inner wall of the roll.

6. A machine of the class described having, in combination, the hollow finishing roll 20 open at one end, the cooperating wedge-faced friction heating members 30 arranged within said roll, the support 26 to which one of said members is connected and the spring 33 tending to move the other member up the wedge face of the first memher to produce friction heating engagen'lent of their outer faces with the inner wall of the roll, substantially throughout its length.

7. A machine of the class described having, in combination, a shaft, a shoe finishing device, a friction device, comprising relatively movable wedge members arranged within the finishing device, means for expanding said friction device against an interior wall of the finishing device, and means for relatively rotating said two de vices for the purpose described.

8. A machine of the class described having, in combination, a shaft, a shoe finishing device, a friction device comprising two members arranged within the finishing device, means acting longitudinally of the shaft to hold said members in frictional contact with the interior of the finishing device, means connecting one of said devices with the shaft to rotate the same relatively to the other device, and means to restrain said other device from rotation.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
